Whenever i got my 2gig sd card from my carrier i stored to device but after a while i noticed alot of issues... So i just bought a 16gig from ebay ..... Then again i was using a 9800

jaysus858, you won't get much from a 2GB SD memory card to be honest these days, so grab the 8GB, 16GB, or the maximum 32GB (not all BlackBerry devices support 32GB) would be the preferred size, plus the cost has steadily gone down.
